ATTACHMENT FOR BOATS.

Application filed March 28, 1922. Serial No. 547,574.

To aZZ whom it may concern:

Be it known that 1, JOHN T. HISERT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Attachments for Boats, of which the following is a specification.

This invention relates to a signaling attachment for boats, and an object of the invention is to provide a buoy structure which is adapted to be carried by-a boat in a convenient location and released for floating to the surface in case the boat sinks.

Another object of this invention is to-provide a buoy structure as specified and a. retaining housing therefor which are particularly designed for use upon submarines, the said housing being accessible from the interior of the submarine in case the latter sinks or becomes disabled beneath the sur face of the water so as to permit the release of the buoy for signaling purposes and to permit determining of-the location of the stricken boat or ship, and also to providea novel form of housing having inlet and outlet valves whereby the controlling of water there into may be regulated to prevent inury to the occupant of the compartment or to the boat by the rushing of water therein when the compartment is open to permit release of the bu y.

Another object of the invention is to provlde an improved buoy construction which has a signaling member detachably support-- ed therein, the said member carrying a suitable fiare by means of which a distress signal may be given and which buoy further has an annular handle thereon to permit the operator to hang to the buoy during the rising of the buoy through the water.

I Other objects of the invention will appear n the following detailed description taken n connection with the accompanying drawlngs wherein:

Fig. 1 is a top plan of a boat showing the improved attachment applied thereto and having the buoy outlet door open.

Fig. 2 is a longitudinal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a section through the buoy.

Fig. 4 is a detail section on the line t-4 of Fig. 3.

Fig. 5 is a view of a modified form of the inyention.

Fig. 6 is a detail section through a part of the modified form.

Referring more particularly to the drawings, a boat preferably a submarine is in dicated at A in Figs. 1 and 2 of the'drawings, and it has. a buoy housing or compartment 1 attached to its upper surfaces, which compartment has a buoy outlet door opening 2 formed in the top thereof, which open ing isfnormally closed by thedoor S'which slides in the guidest and is locked in closed osition by means of the engagement ofthe ocking end 5 ofthe' bolt 6 in the recess 7 in' the under surfaces'of the door. The door 3 has spiral springs 8 connected thereto which are also connected to thehousing 1 through the medium of suitable brackets, which springs'will move the'door 3 into open position'upon release ofthe-locking bolt 6; A handle 9 is carried bythe door to facilitate the closing movement thereof.

Access to the compartment 1. from themterior-"of the boat or submarine A is had through the auxiliary compartment 10 and door 11. A hatchway or 0pening 12 is provided to permit access tothe auxiliary com-.

partment 10. The 'door 11 is normallyclosed, and locked, the locking mechanism being operable from'the auxiliary compartment lO'so as to permit a passenger to pass from the auxiliary compartment into the buoy compartment 1'. A fluid tight closure is provided by the door '11 A buoy supporting stand 14 is carried Within the compartment 1 and it' releasably supports a buoy 15 which is preferably spherical in shape and has a rope or cable 16 connected thereto, which is wound upon a drum 17 so that it will unwind from the drum during the rising of the buoy through the water in which the boat is submerged. The cable 16 is measured oil in predetermined lengths of linear measurement and indicated as shown at 18 so that as the rope or cable pays out from the drum 17 and when the buoy 15 reaches the surface of the water the depth at which the boat is sunk may be readily and accurately determined.

The buoy 15 is hollow and has a removable closure 19 screwed into an arm opening 20 formed in the buoy, the said arm opening being provided to permit access to the interior of the buoy for removing the signaling device 21. The signaling device 21 comprises a tubular handle 22 which telescopically receives the supporting rod 23 securely carried by the shell of the buoy 15. If it is so desired a thumb screw 24 may be provided rial is carried within the buoy at one side asshown at 27.

. An annular handle 28 extends around the buoy. 15 and is provided so that an operator may grip this handle and ride upwardly through the water with the buoy. I

It will beappreciated, by particular reference to Fig. .2 of the drawings that when the door ,3 is open to permit the buoy 15 to pass out of the compartment 1 the water 1 would rush into the compartment and in all probability overcome the operator and possibly injure the boat, but to prevent rushing action of the water an inlet valve structure ofany approved type diagrammatically indicated at 30 is provided which is opened b-ythe operator whenhe enters thecompartment 1 to permit the water to flow into the compartment without. injuring anything therein.,, When the water reaches a proper predetermined levelwithin the compartment the door 3 may then be opened to permit the buoy 15 to pass out of the compartment. An outlet" valve structure 31 of any approved type is carried by the compartment 1 near its bottom to permit thee-draining of water therefrom when desired, and it is to be understood that this outlet valve structure may be constructed in anyapprovedtype to permit controlling of this operation so that the outlet of water from the compartment may be controlled at will.

In-Figs. 5 and 6 of the drawings a modification is shown wherein the buoy structure U is designed for use on ordinary ships for signaling purposes in case of distress .or'

sinking of the-ship. I This modified structure comprises a buoy stand orsupport 40 which is adapted for attachment to the deck of a boat as indicated at B and it comprises resilient or spring fingers: 41 which are adapted to engage about the buoy l5 and inwardly of the annular handle 28 of the buoy as clearly shown in the drawings. The buoy 15 hasa cable 12 attached thereto which is connected 'to the drum 13. The

drum 43 is enclosed in a housing 4A which is provided with a suitable opening 45'topermit the cable to pass therefrom. The buoy 15 is similar inconstruction to the buoy l5 andis adapted to carry a suitable signaling mechanism. WVhen'a ship equipped with the modified form of thebuoy sink-sythebuoyancy of the buoy willcause it to rise and releasing engagement offthe spring fingers or arms therewith, permit it to ascend to the surface of the water.

It is, of course,;to,be understood that the invention maybe constructed in other manners and the parts associated in other 'rela-' tions and, therefore, I, do not desire to be limited inany manner except asset forth in the claim hereunto appended.

Having thus described my invention whatIclaim is: a

An attachment for boatsucomprising a compartment formed on the top of the boat,

signalling means within the compartment, arcuate. shaped guides arranged at the top of the compartment, an arcuateshaped door sliding in said guides, and a plurality ofsprings connected to one edge portion of the door for sliding same to open position.

- In testimony whereofl afiix my signature.
